Triac-Based Motor Controller

Overview

Description

Triac-based motor controllers are well-suited for controlling AC motors, commonly found in household appliances, HVAC systems, fans, and more. As the demand for building automation and smart home technologies grows, there's an increasing need for systems that are easy to integrate, cost-effective, and highly reliable - areas where triac-based motor controllers excel.

This triac-based motor controller design showcases a robust, compact air conditioning system, making it ideal for small-scale applications, including vehicle systems. The triac-based approach simplifies the overall design, reducing manufacturing costs and complexity, which is perfect for mass-produced products.

System Benefits​:

  • Easy implementation with optimized triac control for a simplified compressor motor control system.
  • Flexible system design with low-power, high-performance 32-bit MCUs.
  • A high voltage AC/DC buck regulator converts rectified AC power for simple operation.
  • Enhanced system monitoring for fail-safe protection, sensing current and load.
